CEMENT-POST MOLD.

Specification of Letters Patent.

Application mea January 2s, 1921. serian Np. 440,111.

To all 'whom t may concern: l

Be it known that I, NELs J. JOHNSON, a citizen of the United States, residin at Wallingford, in the county of Emmet, tate of Iowa, have invent-ed certain new and useful Improvements in Cement-Post Molds; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in molding devices and particularly to molding devices forfence posts.

One object of the invention is to provide a mold wherebya corner post, and its braces, may be molded simultaneously, and whereby the mold may be easily and quickly removed when the plastic'material has properly set.

Another obj ect is to provide mold sections for the braces which are capable of adjustment to form braces of different lengths and at different angles withrespect to the post and ground.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation of the improved post and brace mold in position over the holes in the ground.

Figure 2 is a top plan view of the same.

Figure 3 is a perspective view of the mam body or post p ortion of the mold, showing the manner in which the sections are connected together, and also showing the removable smaller section Which permits the ready and easy movement of the larger section from between the points of juncture of` the braces with the body of the post.

Figure 4 is a vertical sectional vievv through the post mold and one of the brace arm molds, on the line %4= of Figure 2.

Y.Figure 5 is a vertical longitudinal sectional view through the mold, on the line 5 5 of Figure 2, passing through the removable larger and smaller sections.

Referring particularly to the accompanying drawings, the main or body portion of the mold, that is the portion in which the post proper is molded, includes the three larger sections 10, 11 and 12, the former of which are hinged together along their longer edges as shown at 13, While the longer edges of the section 12, and the meeting adjacent longer Patented Feb. 21, 1922.v i

edges ofthe sections 10V and 11, are provided .1.;

with the tubular members vforvertical align ing registration to receive the retainingpins 14. The sections 10, 11,and12, When 4thus joined together, form a tube in which the plastic material is poured tol form the body of the post. Y the sections 10 and lljare the laterally eX'-, tending lingers 15 which are adapted to rest on the surface of the ground, at the sidesof the post hole 16, to, support the mold and pDrevent same from dropping into the hole'.

isposed below thelower -end of lthe'fsection 12, which section' is shorter thanthe sections 10 and .11, is a small section 17 )which 4fills Carried -by the lower endsrof in the space below the lower end 4of the se'c tion 12, when the mold is erected overV the. post hole. The wallsof the hole 16 'are' undercut or recessed, as 'at 16', in which some of theplastic material` will How to; formjan anchor for the base of the finished post.

Formed in the ground, at Asuitable distances I from the post, and at an angular distance of ninety degrees from each other, are the inclined holes 18, which serve as the bases of the inclined braces 19, leading from the sidesY of the post 20.

. In two sides of the body mold, which includes the sections 10, 11, and 12, are formed the openings 21, said openings being formed partly in the opposite side portions of the removable section 12, and in the adjacent sides of the sections 10 and 11. Into these openings are inserted the tubes 22, each of which comprises two hinged sections. Telescoped into each of the tubes 22 is a longer tube, also comprising tvvo hinged sections, the other end of each of said tubes 23 being disposed in the upper end of one of the .holes 18, toguide thejplastic material into said holes, and to serve as the molds for thev braces 19 of the post.

The mold being assembled as shown in Figure 1, the plastic material is poured into the top of the main body of the mold, to drop into the hole 16, and when this hole is filled, and the material level rises to the points where the tubes 22 are disposed within the openings 21, the material will then flow down the tubes 22 and 23, into the brace holes 18. When these holes and the tubes 22 and 23 are filled, the rest of the body of the mold is filled, and the material allowed to set. When the material has properly set, the pins 14 are removed, and the smaller section 17 removed from below the section i 12. The section 12 is then moved outwardly and downwardly froml the body of the Viinished post, the walls of the openings in v the ground and thusprevent any downward movement of the section. When the section 12 is thus removed, the sections 10 and 11 may then be swung open for removal from Y the'iinished post, thus releasing the tubes 22 and 23, which are then swung open and disengaged from the braces 18 of the post.

By reason of the telescopic nature of the sections -ortubes 22 and 23, and the fact that the tubes 22 are arrangedto enter the openings 21 at different angles with respect to the body of the mold,`permits said tubes to be disposedat diferentangles to anchor theouter ends of the braces 18 at different distances from the post body.

' What is claimed is: A 1

1. A lfence' vpost mold including a post body mold portion comprising separable sections which when assembled form a tube, a brace mold portion detachably connected to one of said sections, one of the sections being shorter than the other sections, and ar-v ranged below the connection of the brace mold, a small section removably disposed below the said shorter section, 'for removal to facilitate the removal of the said shorter section and the brace mold.

2. lnY a fence post mold a post body mold including tube formed from removably connected sections one of which is shorter than the other sections, the tube having openings in the sides thereof partially in the sides of the removably shorter section and partly in the adjacent portions of the other sections, removable tubular members engaged in the said openings for forming inclined braces for the post body, the said removable section being arranged to be withdrawn from the finished post and braces by a downward and outward movement, and a smallersection removably disposed 'belowthe shorter section and removable to permit the said downwardly and outwardly directed movement of the shorter section.

In testimony whereof, I affix my signature, in the presence of two witnesses.
